General description

Certified pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Sulfapyridine melting point standard, also called Sulfapyridine, is a metabolite of sulfasalazine. It is an antibiotic and is mostly used in treating rheumatoid arthritis. Sulfapyridine is a short acting sulfonamide, which can be substituted for dapsone and it does not cause neuropathy.

Sulfapyridine Melting Point Standard also called Sulfapyridine is a metabolite of Sulfasalazine. It is an antibiotic and is mostly used in treating rheumatoid arthritis.


These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
